This paper applies the cognitive hierarchy model of Camerer, Ho and Chong (2004) to the action commitment game of Hamilton and Slutsky (1990). The model generates the heterogeneity of behavior reported in Huck, Müeller and Normann (2002). The model predicts the spike in the leadership quantity in the first period as well as the spike in the Cournot quantity in the second period. The model predi...

The spike detection problem is cast into a delay estimation. Using elementary operational calculus, we obtain an explicit characterization of the spike locations, in terms of short time window iterated integrals of the noisy signal. From this characterization, we derive a joint spike detection and localization system where the decision function is implemented as the output of a digital Volterra...

Selective attention is an important filter for complex environments where distractions compete with signals. Attention increases both the gamma-band power of cortical local field potentials and the spike-field coherence within the receptive field of an attended object. However, the mechanisms by which gamma-band activity enhances, if at all, the encoding of input signals are not well understood...

The application of advanced multilevel techniques to the solution of the EHL line contact problem has resulted in a multilevel solver of complexity O[n In n). The reduction in computing time thus obtained enables the use of large numbers of nodes and allows detailed study of the pressure spike. Both occurrence and height of the spike as a function of the governing parameters were studied The pa...

We examine the spiking axon as a communication channel. We develop a .rst principles channel model that encompasses the noise in the axon, which manifests itself as spike jitter, and the power consumption, which arises from the activity of the Na–K pump. This model enables us to examine the trade-o4 between the information rate and power consumption. Using parameters from the frog myelinated ax...

Biological phenomenon. Spike-timing dependent plasticity (STDP) in its narrow sense refers to the change in the synaptic strength as a result of electrically eliciting pairs of action potentials (‘spikes’) with a fixed time difference between the preand post-synaptic action potentials (Markram et al., 1997; Bi and Poo, 1998; Sjostrom et al., 2001). STDP is typically observed for synapses betwee...

In this paper the coding capabilities of individual retinal ganglion cells are compared with respect to the coding capabilities of small population of cells using different neural networks. This approach allows not only the identification of the most discriminating cells, but also detection of the parameters that are more important for the discrimination task. Our results show that the spike ra...
